The AMA Fight Club’s Mike Constantino, the manager and one of the trainers for the fighters and brothers, today confirmed the signings with MMAjunkie.com (www.mmajunkie.com).

Both of the fighters signed four-fight exclusive contracts, though financial terms of the deals were not disclosed.

Constantino declined to comment n the particulars of the negotiation process, and he had no comment on the UFC’s rumored purchase of the IFL.

Constantino said no definitive dates have been determined for the Miller brothers’ UFC debuts, but he said they will be available any time the UFC needs them.

“If they told us to fight in two weeks, we’d be ready,” Constantino said. “We’ll fight as soon as possible. The guys are always in shape and in the gym all the time helping their teammates. We have about 20 guys at the gym who fight in pro organizations, so someone always has a fight coming up, and Dan and Jim are always there helping them out.”

Dan Miller, 27, recently won the IFL middleweight title with a first-round submission victory over Ryan McGivern. It was just his second fight in the IFL; he debuted in August 2007 with a submission win over Dave Phillips.

He is also the middleweight champion for Cage Fury Fighting, where he fought before signing with the IFL. The former high school wrestler has scored five of his eight career victories via submission.

Jim Miller, 24, has also had success in the IFL, where he defeated stand-out Bart Palaszewski via unanimous decision in his lone IFL appearance. Prior to that April fight, he fought throughout the Northeast and held titles in a variety of organizations, including Cage Fury Fighting Championships and the Reality Fighting promotion.

The UFC had actually tapped Miller to replace an injured Spencer Fisher at UFC Fight Night 13 in April — but the IFL intervened and said the fighter was already under contract. (Ryan Roberts took the fight with Marcus Aurelio instead.)

The former Virginia Tech wrestler has earned submission victories in all but his first pro win. His lone loss was to UFC lightweight Frankie Edgar in November 2006.

These latest IFL-vet signings come amidst reports of the UFC possibly purchasing the struggling IFL, which has currently suspended operations due to financial troubles. A source close to the UFC tells MMAjunkie.com that the UFC “has [begun] acquiring IFL assets.” Another source said the IFL is in “the final stage of being sold and shut down.”

At least two high-ranking IFL officials have already told colleagues they will be gone from the company by month’s end.

The IFL stock price recently shot up nearly 250 percent on rumors of the sale but has since returned to its normal price of three cents a share.
